6x6 Kropki Sudoku (Mini Sudoku Series #59)

This Kropki Sudoku, I created for my students to learn about Kropki Sudoku puzzle type. Generally 9x9 Kropki Sudoku which does not contain any hints is very tough and its difficult for a new comers especially kids to understand this type by solving 9x9 Kropki Sudoku. This is the reason I created few 6x6 Kropki Sudoku puzzles so that kids can understand rules easily and start loving this puzzle type. I have not yet introduced them to Kropki Sudoku type, however I will soon introducing this new type to them and will some feedback from them on these puzzles.
